The ZPRX740F inclined stem discharge valve is a specialized bottom-discharge solution for reaction vessels, featuring a three-piece modular design (curved flange, intermediate flange, and valve body) for easy installation. Its 105° angled stem prevents actuator interference with the vessel, while the arcuate ball surface ensures residue-free sealing when closed.
The quarter-turn operation provides reliable flow control, making it ideal for chemical, pharmaceutical, food/beverage, petrochemical, and water treatment applications.

| Features | Description |
| One-Piece Body | The flush-mounted bonnet design minimizes the clearance between internal components and the vessel bottom. This configuration effectively reduces agitation dead zones and discharge port accumulation. |
| Self-Centering Structure | Stem blowout-proof design/Static-dissipative device/Fire-safe certified design, delivering enhanced performance and superior structural integrity. |
| Trunnion-Mounted Ball | The 15° angled valve stem effectively prevents interference between the actuator and vessel, while avoiding material accumulation at the outlet. |
| Flat Sealing System | The flanged container bottom features a curved bonnet design that prevents media retention, ensuring smooth flow. This valve is compatible with both curved flanges and valve bodies. |
| Shape－Memory Alloys Seat | Forged-welded plug & stem assembly maintains structural rigidity to prevent stem deflection under maximum thrust load |
| Superior Sealing | One-piece body/bracket ensures stable operation with ISO 5211-compliant actuator mounting. |
| Standard Mounting Platform | The connection shaft is manufactured from Grade 45 steel or 2Cr13 alloy through hot-forging and CNC center machining. Ensuring precise fit and enhanced rigidity. |
